|20140183684||PHOTODETECTOR ARRAY AND METHOD OF MANUFACTURE - The present invention is directed to photodiode arrays comprising a dielectric structure containing an array of face conductive areas (pads) and. Each photodiode is fully separated from each other. Every photodiode has a face electrode formed on sensitive side of the semiconductor substrate and an individual back electrode formed on the opposite side. The number of conductive areas on the dielectric structure is equal to number of photodiodes in the array. The photodiodes of the array are installed on the conductive areas so that their back electrodes have electrical contact with the corresponding conductive area. Each conductive area contains at least one individual conductive hole penetrating the dielectric package from the face side to the opposite side of the dielectric structure. The conductive holes going to backside of the dielectric structure are connected with the back conductive areas formed on back side of dielectric package.||07-03-2014|
|20120061577||DEPTH-OF-INTERACTION SCINTILLATION DETECTORS - The invention disclosed herein relates to a scintillation detector for registering the position of gamma photon interactions, an comprises an array of two or more elongated first and second scintillation crystal elements connected together along their respective long sides, and an array of discrete photosensitive areas disposed on a common substrate of a solid-state semiconductor photo-detector. The array of first and second scintillation crystal elements have proximal output windows optically coupled to the array of discrete photosensitive areas in a one-to-one relationship. The invention may be characterized in that the first and second scintillation crystal elements include a rooftop portion at their distal ends, wherein the rooftop portion optically couples one of the first and second scintillation crystal elements to the other and is configured to reflect and transmit light resulting from a gamma photon interaction from one of the first and second scintillation crystal elements to the other.||03-15-2012|
